Producing Graphical Output (Plots)

Graphical output from AST is performed though an Object called a Plot, which is a specialised form of FrameSet. A Plot does not represent the graphical content itself, but is a route through which plotting operations, such as drawing lines and curves, are conveyed on to a plotting surface to appear as visible graphics.
